PALO ALTO, Calif. — Facebook removed an image of an iconic 1991 Nirvana album cover featuring a picture of naked baby for violating its terms of use, before changing its mind, it was reported Thursday.

The social networking site removed an image of the “Nevermind” cover from the grunge band’s official fan page on the site, according to the Hollywood Reporter.

But the album cover, which shows a naked baby boy swimming towards a dollar bill, was back on the Nirvana Facebook page later, after an apparent change of heart by Facebook.

A source close to the band told Entertainment Weekly, “Facebook took down the product shots, they sent us a form message. I’m guessing it’s probably due to the baby penis … still making waves 20 years later.”

The notice read, “Facebook does not allow photos that attack an individual or group, or that contain nudity, drug use, violence or other violations of the terms of use.”

The baby in the picture, Spencer Elden, now 20, is the son of a friend of Nirvana’s photographer.

He was quoted in a 2008 interview as saying, “Quite a few people in the world have seen my penis. So that’s kinda cool.”

The band’s record label posted the cover to promote a commemorative anniversary edition set to be released on Sept. 27.
